We do not do your work for you. Once you have answered your questions, we will be happy to give you feedback on your work. Although it might require more time and effort, you will learn more if you do your own work. Isn't that why you go to school?

Try factoring the numerical term and the numerical aspect of x^2. See how they would combine to add/subtract to get middle term.

I hope this helps.
